GitHub does a redirect to https:// when you use http://
repology complains with:
“Homepage link "https://github.com/…" is dead (HTTP error 404) for more than a month.”
This will fix some of them (not all though)
* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
First of all, we need a newer version of Vc, because at least version
1.1.0 is required for Krita 3.1.3.
Also, qtmultimedia and qtx11extras were missing.
Built and tested successfully on my machine.

It's necessary to do this in order to fix ckb's compilation, now that
fixupPhase rejects derivation results containing references to the temporary
build directory. It seems like good practice so I've added it to the
other packages that I maintain.
DraftSight is "a professional-grade 2D design and drafting solution
that lets you create, edit, view and markup any kind of 2D drawing."
It is available as a binary .deb package for Linux. This package jumps
through the necessary hoops to make it run properly.
After upgrade `qapitrace` have working "Buffers" tab where the data
can be inspected (it was always empty before).
There is no tags after `7.1`, but I think that fixing pretty important
piece of functionality warrants an upgrade to current `master` tip.
Tesseract 4 has got a new long short-term memory neural networking based
OCR engine which really helps a lot in terms of accuracy and our VM
tests.
I ran the new version across a bunch of different screenshots and
comparing the results to the 3.x branch and it really makes a big
difference, especially with various font rendering settings.
The only downside of this is that version 4 hasn't been released yet and
is in alpha state right now, but it will eventually get there and the
only solutions that came into my mind sticking to version 3 were really
sub-par:
* Use several passes with different color negation on the screenshots.
* Train Tesseract 3 specifically for screenshots. This is sub-par
because we'd need to do it for Tesseract 4 from scratch again.
* Change the test systems so that it specifically uses *only* OCR an
font when displaying. I've actually tried this but this also isn't
accurate enough with our default font rendering setup.
* Turn off special font rendering settings for our tests. In
conjunction with changing to an OCR font this might work but it won't
catch all the cases, because applications might use their own font
rendering.
Given that version 4 is faster[1] when it comes to OCR detection and also
the points just mentioned I think even using the alpha version just for
tests isn't going to hurt anybody.

Upstream changelog:
* Made some fine tuning to the hOCR output.
* Added TSV as another optional output format.
* Fixed ABI break introduced in 3.04.00 with the AnalyseLayout()
method.
* text2image tool - Enable all OpenType ligatures available in a font.
This feature requires Pango 1.38 or newer.
* Training tools - Replaced asserts with tprintf() and exit(1).
* Fixed Cygwin compatibility.
* Improved multipage tiff processing.
* Improved the embedded pdf font (pdf.ttf).
* Enable selection of OCR engine mode from command line.
* Changed tesseract command line parameter '-psm' to '--psm'.
* Added new C API for orientation and script detection, removed the old
one.
* Increased minimum autoconf version to 2.59.
* Removed dead code.
* Fixed many compiler warning.
* Fixed memory and resource leaks.
* Fixed some issues with the 'Cube' OCR engine.
* Fixed some openCL issues.
* Added option to build Tesseract with CMake build system.
* Implemented CPPAN support for easy Windows building.
The upstream URL of the change log is:
https://github.com/tesseract-ocr/tesseract/releases/tag/3.05.00
Tested by building against the following packages that directly depend
on it:
* vapoursynth (with ocrSupport = true)
* pyocr (fails)
* vobsub2srt
Also tested against the following NixOS VM tests that have OCR enabled:
* nixos/tests/chromium.nix -A stable
* nixos/tests/emacs-daemon.nix
* nixos/tests/installer.nix -A luksroot
* nixos/tests/lightdm.nix
* nixos/tests/plasma5.nix
* nixos/tests/sddm.nix
All of the packages and tests except pyocr build/succeed on
x86_64-linux.
Fixing pyocr is outside of the scope of this commit and will happen very
soon.

I've removed that attribute in 68bc260ca2,
because the language files no longer were distributed as seperate files,
but if we for example only want to use the English training data, the
closure size of Tesseract gets quite large (around 1.2 GB), which is a
bit much just to be able to run NixOS VM tests.
For this reason I've also switched the VM tests back to using only the
English language.
Tested using the following VM tests (the ones that have OCR enabled) on
x86_64-linux:
* nixos/tests/chromium.nix -A stable
* nixos/tests/emacs-daemon.nix
* nixos/tests/installer.nix -A luksroot
* nixos/tests/lightdm.nix
* nixos/tests/plasma5.nix
* nixos/tests/sddm.nix
